	All right, thanks to all those who helped me last time, but I'm still
having problems. In DJGPP, before main(), I declare these variables as
global:-

unsigned char *vbuf ;         
unsigned char *doublebuffer ; 
unsigned char *background ;   

	Then, soon as the program starts, I do this :-

 unsigned char *vbuf = (unsigned char *)malloc(64000);         
 unsigned char *doublebuffer = (unsigned char *)malloc(64000); 
 unsigned char *background = (unsigned char *)malloc(64000);   

	But, it causes a general protection fault every single time! I know I am
in-experienced, but surely there is something seriously wrong here? It
compiles without errors but brings down DOS every single time.
	Once again, thanking people in advance,

		-Thomas
